Understanding Ordered Pairs and Graph Interpretation

The video tutorial explains how to interpret ordered pairs on a graph, focusing on the pairs (90, 100) and (0, -50). It describes how the first value represents the input (candles sold) and the second value represents the output (profit or loss in dollars). The tutorial guides viewers through locating these points on a graph and understanding their real-world implications.

What does the first value in an ordered pair represent on a graph?

• The output value

• The vertical axis

• The input value

• The diagonal axis

What does the second value in an ordered pair represent on a graph?

• The horizontal axis

• The output value

• The input value

• The diagonal axis

In the ordered pair (90, 100), what does the number 90 represent?

• The number of customers

• The loss in dollars

• The number of candles sold

• The profit in dollars

If 90 candles are sold, what is the profit according to the graph?

• $50

• $90

• $150

• $100

How is the point (90, 100) located on the graph?

• By moving diagonally to 90, 100

• By moving horizontally to 90 and vertically to 100

• By moving vertically to 90 and horizontally to 100

• By moving horizontally to 100 and vertically to 90

Complete the sentence: The profit will be ___ dollars if ___ candles are sold.

• 100, 90

What does the ordered pair (0, -50) indicate about the profit?

• A profit of $0

• No profit or loss

• A loss of $50

• A profit of $50

If no candles are sold, what is the financial outcome?

• A loss of $50

• A profit of $50

• A loss of $0

• A profit of $0

What does the number -50 represent in the ordered pair (0, -50)?

• The number of customers

• The loss in dollars

• The number of candles sold

• The profit in dollars

What is the significance of the point (0, -50) on the graph?

• It shows no change in profit or loss

• It shows a profit when 50 candles are sold

• It shows a loss when no candles are sold

• It shows a profit when no candles are sold
